Magnetostriction and disaccommodation in Fe85B15
Journal of Magnetism and Magnetic Materials, 1996 Abstract The average number of thermally activated ordering processes 〈N〉T as a function of temperature was determined on amorphous Fe85B15 ribbons, in as-cast and annealed states, using the structural model for the disaccommodation. For this purpose measurements of the saturation magnetostriction, disaccommodation and saturation magnetization were ...

Magnetic disaccommodation of hydrogen and dislocations in metals
Il Nuovo Cimento B Series 11, 1976In ferromagnetic materials hydrogen has been observed to give rise to three types of magnetic relaxations: 1) diffusion aftereffect due to a long-range migration of hydrogen within domain walls, 2) orientation after-effect due to the rearrangement of anisotropic hydrogen-impurity complexes, 3) magnetic cold-work peak resulting from a condensed hydrogen

Photomagnetic effects and disaccommodation in Co-doped YIG
Journal of Physics and Chemistry of Solids, 1975Abstract Y3Fe5O12 (YIG) doped with ≦ 0.01 Co per molecule in combination with small dopes of V or (and) Mn show a decrease of the permeability in the dark (disaccommodation, DA) as well as when irradiated (photomagnetic effect, PE) with white light.

Magnetic disaccommodation in normal spinel structures
Applied Physics A Solids and Surfaces, 1991Magnetic disaccommodation is investigated for ferrous ferrites with normal spinel structure. This study shows the presence of a new relaxation process in the temperature region IV (≃285 K) that has not been detected in inverse spinels. A numerical analysis of the isochronal spectra reveals that it is composed of two simple Debye processes with ...

Coercivity and disaccommodation on amorphous (Fe1−xRx)80B20
Journal of Magnetism and Magnetic Materials, 1994 Abstract Amorphous ribbons of the composition (Fe 1− x R x ) 80 B 20 (R = Y, Ce, Pr, Nd, Sm, Gd, Ho, Er, Tm, Lu) (0⪯ x ⪯0.08) were studied by means of disaccommodation measurements, pinning field and coercivity measurements. The after-effect scales roughly with the square of the magnetostriction constant.

Anomalous magnetic disaccommodation in yttrium iron garnet
Materials Letters, 1998Abstract An alternative approach to account for the oxygen loss at sintering temperatures in YIG allows an explanation to the not yet elucidated accommodation effect observed in the magnetic disaccommodation spectrum of nominal stoichiometric samples below 130 K; i.e., the observed time increase of the initial permeability μ i after ...

Effect of tetravalent substitutions on the magnetic disaccommodation in magnetite
physica status solidi c, 2006AbstractThe relaxation of the initial magnetic permeability has been measured in polycrystalline tetravalent‐doped magnetite with nominal composition MexFe3‐xO4 (Me: Ti, Sn, Si) with 0 < x < 0.4. The samples have been sintered at 1400 ºC in a reducing CO2 atmosphere. The time decay of the initial permeability after sample demagnetization has been
